`data` |
Data frame with the time series information. |

`maxiter` |
Maximum number of iterations for Gibbs sampling. |

`burnin` |
Burn-in period of the Markov Chain generated by Gibbs sampling. |

`thinning` |
Number that indicates how many Gibbs sampling simulations should be skipped to form the Markov Chain. |

`level` |
Flag that indicates if the level of the time series will be considered for clustering. If TRUE, then it is taken into account. |

`trend` |
Flag that indicates if the polinomial trend of the model will be considered for clustering. If TRUE, then it is taken into account. |

`seasonality` |
Flag that indicates if the seasonal components of the model will be considered for clustering. If TRUE, then they are taken into account. |

`deg` |
Degree of the polinomial trend of the model. |

`c0eps` |
Shape parameter of the hyper-prior distribution on sig2eps. |

`c1eps` |
Rate parameter of the hyper-prior distribution on sig2eps. |

`c0beta` |
Shape parameter of the hyper-prior distribution on sig2beta. |

`c1beta` |
Rate parameter of the hyper-prior distribution on sig2beta. |

`c0alpha` |
Shape parameter of the hyper-prior distribution on sig2alpha. |

`c1alpha` |
Rate parameter of the hyper-prior distribution on sig2alpha. |

`priora` |
Flag that indicates if a prior on parameter "a" is to be assigned. If TRUE, a prior on "a" is assigned. |

`pia` |
Mixing proportion of the prior distribution on parameter "a". |

`q0a` |
Shape parameter of the continuous part of the prior distribution on parameter "a". |

`q1a` |
Shape parameter of the continuous part of the prior distribution on parameter "a". |

`priorb` |
Flag that indicates if a prior on parameter "b" is to be assigned. If TRUE, a prior on "b" is assigned. |

`q0b` |
Shape parameter of the prior distribution on parameter "b". |

`q1b` |
Shape parameter of the prior distribution on parameter "b". |

`a` |
Initial/fixed value of parameter "a". |

`b` |
Initial/fixed value of parameter "b". |

`indlpml` |
Flag that indicates if the LPML is to be calculated. If TRUE, LPML is calculated. |

It is assumed that the time series data is organized into a data frame with the time periods included as its row names.

`mstar` |
Number of groups of the chosen cluster configuration. |

`gnstar` |
Array that contains the group number to which each time series belongs. |

`HM` |
Heterogeneity Measure of the chosen cluster configuration. |

`arrho` |
Acceptance rate of the parameter "rho". |

`ara` |
Acceptance rate of the parameter "a". |

`arb` |
Acceptance rate of the parameter "b". |

`sig2epssample` |
Matrix that in its columns contains the sample of each sig2eps_i's posterior distribution after Gibbs sampling. |

`sig2alphasample` |
Matrix that in its columns contains the sample of each sig2alpha_i's posterior distribution after Gibbs sampling. |

`sig2betasample` |
Matrix that in its columns contains the sample of each sig2beta_i's posterior distribution after Gibbs sampling. |

`sig2thesample` |
Vector that contains the sample of sig2the's posterior distribution after Gibbs sampling. |

`rhosample` |
Vector that contains the sample of rho's posterior distribution after Gibbs sampling. |

`asample` |
Vector that contains the sample of a's posterior distribution after Gibbs sampling. |

`bsample` |
Vector that contains the sample of b's posterior distribution after Gibbs sampling. |

`msample` |
Vector that contains the sample of the number of groups at each Gibbs sampling iteration. |

`lpml` |
If indlpml = TRUE, lpml contains the value of the LPML of the chosen model. |
